ingforming'apart hereof. This 'inyention relates to the handlingir of coke in gas plants andin other: coke produc-I -infr plants, and 'especially to apparatus of this general" character inf'whichthe -coke is dischargedl the retorts` into temporary' conta'inersin: which. the' hot 'coke isque'nched by` the. admission of 'wa' ter.- vSuch tempo? rary V containers or: receivers' lare 'usually' placed in; tlieffloor, immediately in i"ro'nt of the beneh'lr'jf Vretortsleya'nd vthe: coke,- :when quenched, isfdischargcd through theb'ottoni veycr i hefcllar of the cokehoiisebelow the floor which vsupportsthe' container.' kThe steam which isjgenera'tedin vthe quenchingis discharged iniinly'ithroughwthe open-tops ofthe. containers.` above theloor` andI it is desirable tliat as littlev steam as possible shall.

escape intoiithe cellar, below the lfloor. where vits presence' would interfere withthe operations which are necessarily carried on there and from which it would pass to other parts of the plant where it would also be objectionable. It is also especially undesirable that air shall be admitted to the hot coke in the temporary container for the reason that the coke is thereby kept in combustion and is consumed while thc heat which is thereby generated soon destroys the, containers= Nevertheless. iu coke quenching apparatus of the kind to which thisl invention relates particularly,the containers, which are closed at the bottom by ordinary swing doors, are liable to become more or lesswarped so that the doors cease to close tightly and considerable steam is therefore permitted to escape into the cellar.'

Tt is the object. of thisinvention to provide for such ltemporary receivers or con-l tainers, in which the hot coke is quenched` practicable water-Sealed doors which can be opened. and closed readily and without interference with any of the operations carried on in theccllar and will ctlectually prevent theadmission of air to the hot coke and the 4escape of steam through the discharge openinLS of the containers notwithstanding the i I Spei'zitcation of Letters Patent.

'I he invention will be more fully ex# plained hereinafter with reference tothe aceo-inpanyingrv drawing in which is illustra ted, and in which i Figure 1 shows. partly elevation and partly 1n vertical section, a portion of a bench of retorts, one of thecontainers supthe bench :of Are- Y 4"ported by the floor below torts, and the improved, watersealed door with its appurtenances, the car into which*l the quenchedl coke is discharged beingalso shown.l Fig. 9j-is afdetail view showing the lever inits open position and engaged by,

I n the. floor' '6, in front of` each vertical se-v ries'of retorts, is supporteda temporary container or lreceiver c. into which the coke from such vertical series of retorts may be disrharged` The open top of each'coi'itainei c may beclosed by'doors ci ande, the latter heini,7 shown as adapted to be supported, as at'4 f, to form a guide to direct the coke into the container.

ing walls to form a. chute, with a comparaf tively narrow mouth. as at c2, through which the coke, when quenched. may be discharged into theI car'or upon the conveyer below. A door g having a vertical flange or walls g', so that. it forms a pan, is supported below the mouth c2 of the container, so that its vertical flangeshall surround the lip c2 of the mouth of. the container.

supported in the position shown in full lines, the pan q forms a water-sealed door for the, container, preventing .the escape of steam and the ingress of air through the mouth oti-A -e container, even. when such mouth has been somewhat warped out of shape. The door is suitably formed so that it maybe swung away from the container to permit the discharge of the quenched-coke, and for this purpose may be supported con veniently-by a lever h which is pivoted at L, preferably -above the lower edge' of the mouth, whereby the door may be swung entirely away from the mouth of the container, as indicated by dotted lines, so as to permit the free discharge of the coke with- The lower part c ofeachcontainer is preferablybuilt with converg Then filled with water, from any suitable source, and` l'io out strikinghthe car or 'conveye'r below. A latch i; pivoted at i', engages a stud h2 on -the iever le' ieheid the deer either in the closed positionfshownby f'ull lines, or in -litheI open position, shown by dotted lines.

The 'door or pan g has a lip or spout q2 through whichv excess'of water Hows into the drip pan g and thence into -the 4trough g* which is common to 4all of the containers.

`1'0 As it is undesirable to dump upon the c oke Y in the car'- below vany part of the water which may remain' in the pan after the quenching, there may be provi ed, as at g, a plug? which may be Awithdrawn before the pan is swungaway in orderlto permit allfof the water which remains therein' tol be discharged in'to the drip pany. ""In theopefration'of quenching coke with A .the improved apparatus, the door or pan g 20 having been swung into closed 'position and there held by the latch i, water is discharged into the 'container 4through the'perforatedI i'pe k and at the same time the' hot coke is iseha ed vintothe containerV from the rc- 'fh'e pan g,' which yusually holdsabout tiinitt to drain.
